Former LAPD officer and U.S. Navy reservist Christopher Jordan Dorner, 33, is the suspect in the killings of Monica Quan, 28, and her 27-year-old fiance, Keith Lawrence, who were found shot to death in their car at a parking structure Sunday night, Irvine police Chief David L. Maggard said at a news conference.

Quan’s father, Randal Quan, a former LAPD captain who became a lawyer in retirement, represented Dorner in front of the Board of Rights, a tribunal that ruled against Dorner at the time of his dismissal, LAPD Capt. William Hayes told The Associated Press on Wednesday night.

Dorner is still at large and is considered armed and very dangerous. In his manifesto he made threats against several people, so hopefully he is captured soon, before anyone else is injured or killed. You can read the entire manifesto here, it is a chilling piece of material of someone who is obviously mentally disturbed.
